Here's a clear comparison between pip and uv:

---

🔹 What is pip?

pip is the default Python package installer.

It's widely used and comes pre-installed with Python (since v3.4+).

Installs packages from PyPI.

Slower compared to some modern alternatives.

Command:

pip install <package>

---

🔹 What is uv?

uv is a blazingly fast Python package manager created by Astral (the team behind Rye).

Built in Rust for high performance.

Meant to be a drop-in replacement for pip + virtualenv + pip-tools.

Can install, lock, and resolve dependencies much faster than pip.

Also handles virtual environments automatically.

Command:

uv pip install <package>

⚙️ Feature Comparison

Feature pip uv

Speed Slower Much faster (Rust-based)

Virtualenv support Separate tool (virtualenv) Built-in

Dependency resolution Basic Advanced + fast

Lock file support No native support Yes (uv pip compile)

Cross-platform Yes Yes

Used by Standard Python users Power users, performance-focused devs

Offline install support Limited Better caching

🔹 When to Use

Use pip if:

You want the standard, battle-tested installer.

You work in a team and need compatibility.

Use uv if:

You care about speed.

You want built-in virtualenv and lockfile handling.

You're experimenting with modern Python tooling.
